To all whom it may concern: 7

Be it known that I, NICHOLAS HEE, of Baldwinsville, in the county of Ononda a, in theState of New York, have in'vente new and useful Im rovements in Vehicle-Springs,

of which the ollowing, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in combined vehicle spring and shock absorber, in which I have sought to combine in a single spring, two sets of s ring leaves co-acting with each other to a 0rd greater resiliency under light loads and gradually increasing resistance under heavy loads, at

the same time to render the vertical movement of the body, both upward and downward, less abrupt as the vehicle is passing over obstructions or uneven pavements.

In other words, my object is to provide a combined spring and shock absorber in a single element, which is not only capable of resisting excessive or sudden down-thrust of the body, but also eases the upward or rebound movement of such body, and preventing excessive strains and breakages of the leaves of the spring. This object, more s ecifically stated, is to provide two semie liptical or bow-sprin s of different initial curvatures, one of whic is termed the bodysupporting spring, While the other is designated as the shockiabsorbing spring, so that when the central portions of the two sets of springs are drawn together by the clamp bolt 18 the shock absorbing spring assists or adds to the resiliency of the body supporting spring to render the action of the latter more easy under a light load, at the same time affording a certain degree of resistance to the upward rebound of the body which is attached to the ends of the lower body-supportin spring.

In t e drawings-Figure 1 is a side elevation of my improved ve icle spring and shock absorber. Flg. 2 is a View similar to Fig. 1,

tlieiclips or loops being omitted. Fig. 3 is an enlarged detail view of one end of the combined spring and shock absorber seen in Fig. "1, showing particularly the manner of attaching the clamps.

This combined vehicle spring and shock absorber comprises essentia a lower bodysupportin spring represented as a whole at -1 an an upper shock absorbin spring represented as a whole at 2, eac spring being of the semi-elliptical or bow-type arched downwardl the center, althoug the up er shock absorbing spring is of less initia curvature than that ofthe lower body-supporting spring.

The lower body-supporting spring is composed of a series of leaves fitting one against the other, when compressed but of different lengths, thetwo upper leaves, as 3, be-- of suitable bands or clips -12, best seen in Figs. 1 and 3, which carry the spring shock absorber. The shock absorbing spring '2- is also composed of a series of leaves,the

lower leaf, as 13, being the longest and having its ends resting inwardly upon the upper faces of the opposite ends of the upper member of the body-supporting spring 3 close to the eyes 4'-, so that when the central portions of both sprin s are drawn together by said clamping bo ts, a certain de gree of tension is exerted the upper spring 2 upon the ends of the body-supporting spring .1 to render the'latter more resilient under a light load. The remaining leaves, as 14, '15, and 16-" of the shock absorbing spring .2 are arranged successively, one upon the other, and upon the leaf 13, and gradually decrease in length 'from the bottom upward, with their ends so arranged relative to the eyes 10 and clips bearing over and supporting all the ends of all the leaves. I

The clips -12 are disposed in substantially radial lines with reference to the arc of curvature of the springs -1 and -2-,

and while the ends of the leaves of the spring -2- are free to slide upon each other, and upon the leaves of the s ring -1 to which they are not attached y the pins 1l-, they nevertheless serve to hold all of the leaves of both springs in contact with each other.

It will be seen from the fore oing description that this combined vehicle spring and shock absorber is particularly simple in construction and effective in operation, both as a shock absorber, to prevent sudden vertical from the ends toward movement of the body of the vehicle, and also to increase the resiliency of the bodysupporting'spring under a light load, as well as to increase its resisting power under a heavy load.

What I claim is:

A spring of the class described,'comprising a body portion formed of a plurality of superposed leaves of upwardly increasing lengths and with eyes at the ends of said body portion leaves, means for connecting said body portion at the ends and centrally thereof to a vehicle, a shock absorber com rising a plurality of leaves of downwar ly increasing lengths and bearing upon said body portion,

U-shaped clips bearing over the respective leaves of said shock absorber at their ends l and likewise over the adjacent portion of the body portion, and pins connecting the terminals of said clips through the eyes of the 20 body portion leaves.

In testimony whereof, I have hereunto signed my name in the presence of two attesting witnesses, at Baldwinsville in the county of Onondaga, in the State of New 25
